Step 2: We have a formula for calculating the average slope of a function that is: A = (f(x) âf(a)) /(x â a), 'A' represents the average slope. Here (x-a) is used to represent the change in input values and f(x) â f(a) is used to denote the change in output of the function f(x).
This value is expressed in hours and represents the number of hours before the lamp is at half its original brightness. The expected life of a lamp will vary based on the lamp technology and the projector; however, most projectors offer about 2000 hours. The lamp's success rate is based on a bell curve, so that a majority of (but not all) lamps will meet the lamp life hours specified.
